In the ESS SABRE chip white paper, the authors talk about how the operation of the on-chip SPDIF decoder creates noise that potentially results in jitter effects on the output, even though the output clock is completely independent of the input (e.g. when the ASRC is enabled), confirming your comments about on=chip leakage.
It does seem, however, that multiple levels of reclocking of all signals, if done on separate circuit boards run by separate power supplies ought to get rid of any jitter effects on the input, i.e. reduce the coupled jitter spectrum to below the residual jitter of the master clock.
